asked questions

Step 1: Shampoo client’s hair twice or thrice with GK pH+ Clarifying Shampoo. Step 2: Apply ¼ inch away from roots, massage into each section and comb for even distribution removing the excess product from the comb. Step 3: Blow dry client's hair until it’s 100% dry. Step 4: Flat iron to smooth out and seal the cuticles. The product should be left on for 48 hours and the hair should not be played with.

There shouldn’t be a wait time: blow drying should follow the treatment immediately.

The temperature on the iron should be 375 to 420 degrees Fahrenheit (180 to 230 degrees Celsius). However, based on your professional judgement, you can increase the temperature to 450 degrees Fahrenheit. We also recommend using GK Hair Titanium Plate flat irons during the application of GK Hair Juvexin Treatments

Miami Bombshell has a different application process than Resistant/Curly and should be followed for optimal results. Step 1: Shampoo hair twice with the GK Hair pH+ Shampoo before the application. Step 2 Section the hair. Step 3 Apply GK Hair Miami Bombshell evenly throughout the hair with an application brush. Make sure the treatment remains 0.5cm from the scalp. Remove excess product from hair using a fine-tooth comb. Step 4 Cover with a plastic cap and sit for 5-30 minutes under the heat. Step 5 Rinse to the point when water runs almost clear. Step 6 Blow-dry with Round Brush until 100% dry. Step 7 Flat iron the hair to seal the cuticles. Step 8 Wash hair with GK Hair Silver Bombshell Shampoo. Step 9 Style as desired!

We recommend waiting because it takes 48 hours for Resistant to form a stronger bond with the hair cortex. If the hair is washed right after the treatment, some or most of the treatment may get washed out and the results may not last as long as desired.
